Dear Michael Miller,
Thanks for your message. You have the advantage over me as it was some
50 years ago that I was at the R.B.G. Edinburgh, and you jolted my
memory regarding things! I almost said how soon we forget, but 50 years
is a while! So perhaps there is a reason for forgetting such things. Now
I remember why pines have sunken stomata and a host of other such
adaptations of plants all contributing to them being able to withstand
adverse conditions, Thanks, I needed that! Cheers and good wishes for
2005. Here in California we are getting enough rain to satisfy us for a
while, yet more is on the way. John E. Bryan
